      Anyone know why JS Iterators (eg MapIterator, SetIterator) didn't get .map(), .reduce(), .filter(), etc? Seems like there must be a reason

      To clarify, I'm also curious why Map and Set themselves didn't get .map, .reduce, .filter, etc, but got .forEach (which seems least useful)

      I advocated for forEach as a transitional step when Maps had landed in browsers but not for/of.

      Did the conversation in this thread just never get returned to? https://github.com/rwaldron/tc39-notes/blob/master/es6/2014-11/nov-19.md … Lack of fp-style interface to collections seems odd

      I'm interested in pushing for flatMap to getting added to collections other than Array (an Array is proposed atm)

      flatMap on instances of Set/Map or their .entries()? What gets flattened? Personally would love reduce/filter/map on Set.proto & Map.proto

      Instances. Entries are just an Iterator (which could also have flatMap) but you want sets to flatten into sets.

          Oh I see. I was definitely imagining the default return value of any collection function would be an Array. Hadn't considered Map -> Map

          It's kinda like jQuery().children(), which wants to produce a new jQuery, not Array.
